However, when applied to the installation of spatial special-shaped curtain walls, due to the particularity of the spatial special-shaped curtain wall structure, the sealant at the connection between the curtain wall panel and the curtain wall frame is easily pulled by the structural stress and cracked, which leads to the loose connection between the curtain wall panel and the curtain wall frame, affecting the overall aesthetics, safety and sealing of the curtain wall. To this end, the present application discloses a curtain wall installation structure based on BIM, which mainly adopts the following schemes: The embodiment of the present application discloses a curtain wall installation structure based on BIM.

[0024] Reference Figure 3 The transmission assembly is used to drive the block 52 to slide. Specifically, the transmission assembly includes a slider 54 and a connecting rod 55. A sliding groove 56 is opened in the connecting rod 5 along the length direction of the connecting rod 5. The slider 54 is slidably set in the sliding groove 56. The side walls of the sliding groove 56 are respectively provided with connecting ports 561 connected with each accommodating groove 53. A connecting rod 55 is arranged in each connecting port 561. One end of the connecting rod 55 is hinged to the slider 54, and the other end of the connecting rod 55 is hinged to the corresponding block 52. A through hole 57 connected with the sliding groove 56 is opened on the connecting rod 5 along the length direction of the connecting rod 5. A locking bolt 58 is penetrated in the through hole 57, and a threaded hole matched with the locking bolt 58 is arranged on the slider 54. During installation, by inserting the locking bolt 58 into the through hole 57 on the connecting rod 5 and screwing the locking bolt 58 into the threaded hole on the slider 54, the slider 54 can slide toward the upper side wall of the slide groove 56 as the locking bolt 58 rotates, thereby driving the clamping block 52 to slide out of the receiving groove 53 and slide into the sliding groove 12 to achieve fixation. A compression spring 59 is also provided in the slide groove 56, and the compression spring 59 drives the slider 54 to slide out of the receiving groove 53, thereby driving the clamping block 52 to be fixed in the clamping groove 12.
